Goodbye CEL. It's no secret that a check engine light on the dashboard will get on anyone's nerves, car lover or not. Modding your S550 EcoBoost should be fun, not riddled with setbacks in an effort to get upgrades installed without an annoying CEL flashing. If you're fabricating a custom BOV for your 2.3L, you'll need this CEL Defender Plug crafted by Turbosmart for a smooth transition. Disconnecting your stock BPV will trigger the dash light, as it's electronically designed to let the factory sensor know the turbo is functioning properly. Using this resistor plug, the CEL will be eliminated when switching to a BOV assembly.

Direct Replacement. If you're currently running an aftermarket Turbosmart Kompact Blow Off Value Kit, this Defender Plug will be an exact replica as the one found in your kit. If the original fails, simply unplug the defective unit and replace using this new connection. If you're building your own custom BOV system for your EcoBoost, this resistor can be plugged right into the factory bypass valve (BPV) sensor connection with the same results. A simple install leaving no pesky check engine light on your dash.

Application. This Turbosmart BOV CEL Defender Plug is designed to be a direct plug and play replacement on 2015-2019 EcoBoost Mustangs equipped with a Turbosmart Kompact Shortie BOV Kit. Also perfect for those EcoBoost owners building your own custom BOV system.

Ok, after installing my BOV my '15 ecoboost mustang check engine came on, after messing around (disconnected battery) with it and flashing it with my Cobb tuner the check engine light has no longer became an issue, however if I scan for faults with my tuner a P0035 code shows? Does this just refrain the check engine light from lighting? Or should I just go back to my stock setup

Every tuner will go about making the CEL not come on for these modifications. In order to better understand this we would need to know if the code is showing active, or stored/inactive. Please contact our Customer Service Department so that we may best assist you with this.

Ok I got the cape cold and hot charge pipes with the tial blow off valve. Got them from CJ pony parts, witch won't go to that site anymore. When I bought the kit did not say anything about needing bov cel defender. They do not sell them on the site eather, without it the engine light will come on. I'm glad that American Muscle sales this product. Install is plug and play, takes less than 30sec., and no more engine light. I will be doing the rest of my shipping from this sight, thanks American Muscle for the great parts and service.

If you are going to install any blow-off valve this is a must have. My 2015 ecoboost Mustang even though no check engine light on, if you looked for continuous DTC it was popping a P0035(turbo bypass pressure to high). This code is not always easy to find, Ford is notorious for not playing well with code readers. This 2 second plug and ziptie job gets rid of that code.

Bought this for the CP-E Exhale kit. Moving the BOV to the cold side caused a CEL because it left the plug hanging. It cleared the CEL but however did not fit properly. It almost feels like the plug didnt go in all the way, no pun intended! Shrink wrap feels very secure

If you relocate the BOV to the cold side charge pipe, you need this this to prevent the CEL that will result from unplugging the PCM from the stock hot side BOV, Very easy install, takes all of 5 seconds to do.
